As a "collector" of shaker bottles, this idea is a very soothing one. I collect all types of shakers for looks, materials, convenience, and necessity.

This shaker fits multiple topics as to how well it looks and performs. The material is plastic, safe to put in the dish washer and easily clean. The lid snaps in four ways which stays sealed through all of the shaking and dropping.

Inside, instead of using a ball or cone, there are two flat red pieces which are honeycombed to mix the contents up. There is a small stick pointing upwards to easily remove the two for cleaning.

On top of the lid, there are two snap lids with different colors to identify which side you put whichever liquid in. Both lids snap and seal in place well, though an extra push is needed sometimes.

The contents mix well with little to none sticking on the bottom. For the price and the idea of this type of shaker, I recommend to add this to your collection.

I was really excited to get this product especially since it said that each side held 14 ounces and i figured that it was perfect for my protein shakes which tend to hold 3 scoops per shake which is 60g of protein. However, each side technically does have 14 ounces but that is once you're past the top line which actually only measures up to 12 ounces and if you actually go any further than that, there is no air space left in the bottle to shake so i had clunky protein for a couple of uses but now i have to put less protein in this bottle due to that issue. Furthermore, I do use my preworkout for one side and protein for the other which i do have to say helps since i wont need to haul extra protein bottles with. But overall, I still think it's a pretty solid product but i just wish the lines actually measured up to at least 14 ounces or more.

Overall I can't recommend the shaker, I really wanted this to work but it leaked less then a month of onwning it. If it could be redesigned where the lid is secured better and maybe have some sort of screw on lid, I think this would be a great shaker bottle.

PROS
The convince of having two different drinks mixed in one cup.

CONS
Leaked within one month of owning it.
The lid really doesn't inspire confidence I always feel like I am going to accidentally pop it open at the gym.
Also If you don't like your Pre/Post workouts really strong don't buy this due to the smaller space for water it makes your mixes very strong.

Love the idea! Good plastic material. Convenient to use. However, each size is 14 ounces once you close the cap and fill the water. When the cap is out, it holds less water, maybe 10ounces? Here is the thing.. i put 2 scoops of protein in one sode and filled with wayer when the cap was open (10ounce).. shaked it (shakes well btw).. it was toooo thick. I had to close the cap, drink some and fill with more water when the cap was closed. And it was perfect. You can close the cap and then fill woth water to the top (14ounce), but that wouldnt work because you need alme shaking space). Overall, ill give it 4 stra outta 5.. happy with the purchase. Just needs to be bigger..

I decided to switch the style of bottles I buy because the traditional blender bottles I use keep breaking around the threading. These bottles look nice, the screen at the top is a nice change from the spring ball, although I believe the spring ball is more effective. On the blender bottle the protein gets stuck around the pouring spout on these it gets stuck in the bottom. Narrow base is good for the cup holder, but terrible to clean out, unless you have alien fingers you need a bottle cleaner. I thought they would be large enough to accommodate 2 drinks but honestly, BARELY! With my protein I measure out 8 ounces of water and I need 10-14 ounces but there's no room for powder if I try for 10 ounces. It raises the level above the screen and doesn't blend well. Works fine for Preworkout, and works fine as a water bottle. It does work for protein powder it just needs a little more work with my routine. I like the latches or threading but I'm wondering how they will hold up.
